To all whom 'it may concern:

Be it known that I, Care B. YAW', citizen of the United States, andresident of Arlingv ton, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

My invention relates especially to what is commonly termed tally stripmechanism for typewritmg machines, and its object, generally stated, isto provide improved devices of the class specified.

To the above and other ends, my inventi n consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

The accompanying drawings show one form of my invention as a plied tothe platen frame or carrier of a o. 11 Remington typewriting machine.

Figure 1 is a fragmentary top plan view of the platen and platen frameor carrier with my invention applied thereto. Fig. 2 is a fragmentaryfront elevation bf the righthand. end portionof the same. Fig. 3 is avertical sectional view taken transversely of" the platen and lookingtoward the ri ht. Fig. 4 is a view corresponding to,-Fig. 3 ut showingsome of the parts in difi'erent relations, other parts being omitted.fragmentary detail end view of the tally strip line spacing devices.Fig. 6 is a fragmenta sectional view taken on planes represente by thebroken line as in Fig; 3 and lookin in the direction of the arrow atsaid line. ig. 7, is a. transverse sectional view of a lat-en showing amodified construction of in ing device for the tally strip. Fig. 8 is afra entary faceview of the platen show-n in ig. 7, parts being brokenawaTheplaten frame or carrier'o theNo. 11

Remington machine is mounted ona carriage (not shown) and is com "os'edof a'rear bar 1, side or end bars 2 an 3 and a cross 7 bar '4 connectingthe end bars below the platen 5, the axle 6 whereof bears in the saidend bars (Figs. '1 td ,4). At its ri lit-hand rend, the platen. isprovided with t e usual line spacing ratchet wheel 7 with; which aroller detent 8 coiiperates. line spacing pawl-9 is mounted on anarid-10 pivoted to the platen axle 6. The, aw'lii'is caused to engagewith the teeth of eratchet wheel and Fig. 5 is a turn the platen by handcontrolled line spacing devices including a forwardly extending link 11.Angular arms 12 are secured to the cross bar 4 and provide bearings attheir upper ends for a rock shaft 13, said rock shaft also bearing inthe end bars 2 and 3. The rock shaft supports the rear end of a paperapron 14 that extends forward around the under side of the platen and isformed with openings through which the sections composing the front andrear feed rollers 15- and 16 are protrusive to contact with the platenor the paper thereon. The feed roller shafts are supported at oppositeends of arms 17' pivote at- 18 on three-armed members 19 supported on arod 20 secured to the angular arms 12. Each member 19 has an upwardlyextending arm 19 which is engageable b a finger 21 secured to the rockshaft 13. aid members 19 also have downwar extendin arms 19 con'ne'ctedto draw springs 19". T e rock shaft 13 near its lefthand end is providedwith an arm or finger The parts thus far referred to are common to theNo. 11 Remington machine and need notbe further described. V The tallystrip devices to which my "pre out invention more especially relates.are

supported on aframe or bracket 23 rovided wit two downwardly extendingranches or fingers 23 which receive screws 24 whereby the bracket isdetachably secured to the end bar 3 (Figs. 1 to 4). From its pointsframe 23 extends upwmrdand forwardsover the top of the platen and inwardor leftward toward the middle thereof, so that the tally stri rollswhich are supported at the upper endortion of said frame or bracketare'dis above the laten and somewhat tor-the" ieft of its rig t-handend. These tally stri rolls are shown in detail in Fig. 6. The eliveryroll 25, which is the lower roll and is arranged somewhat to the rear ofthe receiving roll, isjournaled ona rod or arm 26 which isdetachablysecured by a. nut 27 t0 the bracket 28 and projects horiof attachment tothe end bar the supporting zontal'ly inward therefrom. A sto or crossarm 28 is suitably secured to the left-hand end of the rod 26 and theroll. is )ressed against, the stop by a coiled sprin 9 surrounding therod 26 at the right 0 the roll, said 001 ed spring acting against aWasher 30 which contacts with the end of the roll. The construction issuchthat the washer 30 and cross arm 28 exert sullicient frictionagainst the ends of the roll to revent it from rotating too freely andunwmding the tally strip to an unnecessary extent. The roll or core iece25 is shown solid and may be of wood, ut of course may be otherwiseconstructed and of different material if preferred. The upper orreceiving roll for the tally strip is shown as comprising a hollowtubular body 31 having end pieces or plu s 32 and 33 suitably secured inits enc s. These plugs areperforated to receive a rod or arm 34 whichpro'ects inward parallel to the rod 26 and is et-achably secured to thebracket 23 by a nut 35. A nut 36 at the inner end of the rod 34 reventsaccidental detachment of the receiving :"011 and hand. The tally strip38 is wound on thedelivery rollor core piece 25 and, as shown in Figs. 3and 4, is led down from the back of the roll 25 around the platen andupward at the'front of the receiving roll to which the free end of thetelly strip is or may be attached by a finger or clip 39 which issuitably secured to the tubular part 31 by a rivet 40 and extends lenhwise of said tubular portion from whic it is only slightly separated.An arm or rod 41 is detachahly secured by a nut'41 to an extension 23 ofthe bracket 23. Said rod 41, which is shown as hexagonal, extends inwardparallel with and below the rod 26'and has a reduced cylindrical portion41" which provides a hearing fora combined support and guide in the formof a flanged spool 42. This spool is prevented from being accidentallydetached from its hearing by a nut 43 and rovides a support for an endless transfer band 44 which is or may be an ink ribbon. The endlessinklug band is hung on the spool 42 and-extends downwardly therefromaround the platen which it partially surrounds inside the tally strip38. The tally strip and the inking band are preferably of substantiallythe same width, and the tally strip overlies the inking band which isinterposed between said tally strip and the surface of the platen.

'a feeding of the inking ban Preferably the platen sheath is cut away toprovide a shallow circumferential groove or depression 45 which receivesthe inking band and tally strip so that where these elements hug theplaten they do not project beyond the surface thereof. This constructionenables the wide work sheet or invoice (not shown) to extend widthwisethrough substantially the entire length of the platen and, over thetally stri and inking band without being caused by the latter elementsto bulge at the lace where said invoice passes over them. t also enablesthe-invoice or bill sheet to be line spaced by the regular line spacingdevices w thout line spacing or otherwise afl'ectin 'th'e tally strip.\Vhe'n, on the other han the tally strip is line spaced or fedlengthwise it is not impeded by the invoice sheet which overlies it. A.spring arm or detent 46 is secured by a screw 47 at the rear of the arm41 and extending upwardly therefrom engages the teeth of the ratchetwheel 37, Wh10l'l ratchet wheel, it. will be recalled, is into ml withthe tally strip receiving roll. T e' detent 46 and ratchet wheel 37cooperate to maintain or hold the tally strip receiving roll inpositions in which it may be adjusted. The delivery tally strip roll, itwill be recalled, is frictiohally controlled. The consequence is thatslack in the tally strip between the rolls is prevented and the tallystrip is a]: ways taut. .VVhenthe tally strip is ad'- vancedeither'forward or backward it slips or slides over the band 44 which isnot advanced by these movements of the tallystrip. The engagement of theinking strip. or band 44 with the depressed face of the' platen is,however, sufliciently ti ht to cause if when the platen is turned forline spacing or other purposes. Because of this frictional feeding ofthe inking band by the platen during line spacing movements thereof, itwill: be understood-that different portions of the inking band willreceive the impact of'the' printing types for the different numberswritten on the invoice and tally strip. Means are preferably providedfor autonmtically advancing or line spacing'the tally strip, these meansin the present instancev heing' actuated by the operation of thereleasing arm 22. Said means com rise an arm 48 which is pivotallymounte, on the rod 34 at the right of the fiange34" against which it ismaintained by a. washer 49.,

-Pivoted on a screw 50 carried by't-he free end of the arm 48 is a pawlmember 51 hav-. ing a hub 52 which bears on the screw 50. The member 51is provided with a pawl tooth 53 which is normally maintained in,engagemm t with one or another of the teeth of the ratchet wheel 37 by acoiled, spring 54, said spring surrounding the hub, 59 and having one ofits endsspflin-na L. o f,

arm 48 and the other o'f its ends secured to the pawl member 51. At theside of its pivot opposite the pawl tooth 53, said pawl member 51 isprovided with a laterally disosed finger iece 55. By depressin this ngerpiece the pawl tooth may he disenaged mm the ratchet wheel 37,permitting ackward and turning movements to be given to the. tally stripreceiving roll by and. An actuating link 56 has 1ts upper end pivotallyconnected by a shouldered screw 57 to the arm 48 and extends downwardand rearward behind the platen, the lower end of said link 56 beingpivotally connected at 58 to a crankarm 59. Said crank arm extendsupward and rearward from the rock shaft 13 to which rock shaft it issuitably secured in fixed relation. The rock shaft restoring spring 23normally maintains the crank arm 59, link 56 and arm 48 in the positionsshown in Figs. 3 and 4. When at the completion of the writing of aninvoice, the release arm 22 is pushed rearward, turning the shaft 13rearward and 2 releasing the 'feed rolls so that the invoice may bereadily withdrawn, an automatic advance ofor line s acing of the tallystrip will be effected. he rearward turning of the rock shaft 13 turnsthe crank arm 59 to which pulls the link 56downward, thereby swin ingthe arm 48 and causing'the pawl mem er'51 to advance the ratchet wheel37 and tally stri receiving roll a single space.

The norma positions of the feed rolls,

{ the release arm 22 and connebted parts, in-

4 of thefbody of the invoice and durin thereafter w .ties are operated aouble lmprint of eachthe line spacing thereof, the tally stri wi 1 not"be written upon, her will its re ation with the, rintin point bechanged. Ihe writing of the ho y of the invoice, of course,

0 is effected through the usual inking ribbon (not shown). .When thetotal or other megnoranda "is 'to' be printed on the tally strip; thedepressed .portion 45 of the platen is brought opposite the printingpoint .and

ien the rinting instrumentali- 'ivill take lace. .The invoice will beprinted m'as usual through'the main or ordinary ink-ribbon while theback of the tally strip 0 will reeeive iinpi'ints from, the underlyingaukiliaryinking ribbon 4:4. The tally stri employed is of tissue or,other thin material so thatthe im rints made 011 the back there bf mayeasily e read through the telly strip 5 from the front, When theinkinghand'44,

. and the tally strip has been exhausted it may readily be replaced by afresh inking band.

In Figs. 7 and 8 I have shown another form of inking device for thetally strip,

which form may replace,if desired, the inking band 44.. In the modifiedcon truction the platen 5 is depressed eirciunfcrcnthilly, as indicatedat 60, and at the sides of the depression are formed slightly deepergrooves 61. An inking hand or strip (314 is wound one or more timesaround the depressed surface of the platen at (50 and the side edges ofthis inking band are fastened in the grooves 61 in any suitable way asby pins 63. It will he noted in Fig. that the. heads of these pins 63are below the printing surface of the inking band (52. it will also beseen that this modified inking hand is in fact an endless band whichwill be turned with the platen when thclattcr is line s aced. When theexposed surface of the in ring band is exhausted, the used por- -tionmay be disconnected from the platen and unwound until a fresh portion isex posed, the used portion being cut oil and means for automaticallyline spacing the.

tally, strip; and also that, broadly speaking, an endless inkin ribbonis not new. Aeeordingly it wil be found that I do not claim thesemattersbroadly in the accompanyin claims but only in combinations which0 early distinguish from the prior art.

Various changes may be'madc without dc parting from the spirit of myinvention.

\Vhat I claim as new and desire to secure by Letters Patent, is

1. In a t pewriting machine, the combination of a pl aten, paper feedingdevices 006 erative therewith to feed a work sheet, a tal y strip s uporting device, an inking band interpose between the tally strip andsaid platen, said inking band being independent of said paper feedingdevices, means for advancing said tally strip independently ofsaidplaten, and means for turning the platen in line spacing directionand thus automatically advanein said inking band independently of the ta1y strip.

2. In a tylp'ewriting machine, the combination of-a p a-ten, paperfeeding devices co operative therewith to feed a work sheet, tall-ystrip rolls arranged above said platen and carrying a tally strip whichpasses from one 'rollvaround ,the platen to the other roll, controllingdevices 'for each of said rolls, an
